[Prediction of length and width of upper central incisor tooth in multivariate face information].

Abstract

The possibility of accurately estimating a tooth crown length and width from measured distance of various face points was examined by using Multiple Correlation Analysis. The multiple correlation coefficient between a tooth crown length and the face point was 0.3137 and the residual standard error was 0.820; that between a tooth crown width and the face point was 0.3917 and its standard error was 0.467, obtained by substituted sample data for multiple regression equation.
